Engine Running

Indicates whether the engine is running or not. The electrical power steering module (EPS) receives the engine status signal via the CAN network from the engine control module (ECM). This signal uses the electrical power steering module (EPS) to start the pump motor (the power steering function). The pump motor normally only runs when the engine is running.

YES = Engine running.

NO = Engine not running.

HINT: If the engine status signal from the engine control module (ECM) is incorrect or absent for any reason, the engine speed (RPM) signal from the engine control module (ECM) will be used by the electrical power steering module (EPS). If the engine speed (RPM) signal is also absent, the pump motor will start directly after ignition on.
